Answer 1

Answer: $√(3x-5)-2=0$
add 2 to both sides
$√(3x-5)=2$
square both sides
3x-5=4
add 5 to both sides
3x=9
divide 3
x=3

What expression is not equivalent to 1/343 A. 7-1 x 7-2
B.77 x 7-10
C. 7-2 x 7-5
D. 7-5 x 72
(All expressions have an Integer either negative or positive u just can't type it correctly here and B and D or not 77 or 72 it's 7 and positive 7 and D is 7 positive 2

Answers

1 / 343
This is just equal to
1 / 7^3 = 7^-3

A. 7^-1 * 7^-2 = 7^(-1 + -2) = 7^-3
B. 7^7 * 7^-10 = 7^( 7+ -10) = 7^-3
C. 7^-2 * 7^-5 = 7^(-2 + -5) = 7^-7
D. 7^-5 * 7^2 = 7^(-5 + 2) = 7^-3

So the correct answer is letter C. 7^-2 * 7^-5

i need help on here how to solve it

Answers

Professor Dan Healy, one of my Engineering instructors back in prehistoric times, had a favorite way of showing us how to do this kind of problem ... I mean the kind that's incredibly easy, but your own fear gets in the way and convinces you that you can't handle it. Here is Prof. Healy's method.

For a few moments, call the square root of 5 by the name "cow".

cow - x = 4 . Solve this equation for 'x' :

Add 'x' to each side of the equation: cow = 4 + x

Subtract 4 from each side: cow - 4 = x

Now, we can put the real value back in place of 'cow' : √5 - 4 = x

That right there is a perfect solution. But If you absolutely need to
know the number, then grab your calculator:

√5 = 2.2361 (rounded)

x = √5 - 4 = 2.2361 - 4 = -1.7639 (rounded)

$\sqrt5-x=4\n x=\sqrt5-4$
