What is 2/3 of 8 please help me

Answers

In math, there are a few words to keep an eye out for because it will give you directions for your equations...

"of" means times (×)
"is" means equals (=)

So you translate you sentence into an equation...

What is 2/3 of 8
what = 2/3 × 8

2/3 × 8 =
2/3 × 8/1 = 16/3

now reduce... 3 goes into 16 five times with 1 left over...

16/3 = 5 1/3

Which choice is equivalent to the quotient shown here when x > 0?√72x^3 divide by square root of 50x^2

Answers

Answer:

$(3√(2x))/(5)$

Step-by-step explanation:

Starting point:

$(√(72x^3))/(50x^2)\n$

1) Factor it by Prime Factor Method 72 and 50

$72|2\n 36|2\n 18|2\n 9|3\n3|3\n 1\n 72=2^2*3^2*2$

$50|2\n 25|5\n 5|5\n 1\n 50=2*5^2$

2) Plug it in the factored form. Every exponent to the second power will be outside the radical, so its roots.

$(√(72x^2*x))/(50x^2)=(6x√(2x))/(5x√(2))=(6√(x))/(5√(2))$

3) Rationalize it multiplying by the radical, so that you can eliminate the square root on the denominator.

$(6√(x))/(5√(2))*(√(2))/(√(2))=(6√(2x))/(10)=(3√(2x))/(5)$

What's 49 to the power of 1/2?

Answers

Further explanation

We certainly already know that 49 = 7².

To be able to answer this question, let us use one of the following exponent properties.

$\boxed{\boxed{ \ (x^a)^b = x^(ab) \ }}$

$\boxed{ \ = (49)^{(1)/(2)} \ }$

$\boxed{ \ = (7^2)^{(1)/(2)} \ }$

$\boxed{ \ = 7^{2 * (1)/(2)} \ }$

$\boxed{ \ = 7^1 \ }$

Thus 49 to the power of ¹/₂ equals 7.

- - - - - - -

Now we relate rational exponents with the root form.

In general,

$\boxed{\boxed{ \ x^{(m)/(n)} \rightleftharpoons \sqrt[n]{x^m} \ }}.$

Especially for $\boxed{ \ x^{(1)/(2)} \ }$ will be $\boxed{ \ √(x) \ }$

Based on the above properties, 49 to the power ¹/₂ can be written as,

$\boxed{ \ (49)^{(1)/(2)} \ } \rightarrow \boxed{ \ √(49) \ }$

We state it as 'the square root of 49'.

Thus the result is $\boxed{\boxed{√(49) = 7 \ }}.$

Another example:

What's 100 to the power of ¹/₂ ? The answer is $\boxed{ \ √(100) = 10 \ }$

By the use of exponent properties we get, 7 is 49 to the power of 1/2.

Let us use one of the following exponent properties.

(xᵃ)ᵇ = xᵃᵇ

$49^(1/2)$ = $(7^(2))^(1/2))$

2 * 1/2 = 2/2

= 1

7¹ = 7.

Therefore, 49 to the power of 1/2 is equal to 7.
