Evaluate b2c-1 for b = 8 and c = -4. -16 1/16 16 256

Answers

Answer 1

Answer:

Answer: The correct option is (B) -16.

Step-by-step explanation: We are given to evaluate the value of the following expression for b = 8 and c = -4 :

$E=b^2c^(-1).$

To find the value of expression (i), we need to substitute the values of b and c in equation (i).

We will be using the following property of exponents :

$x^(-a)=(1)/(x^a).$

Therefore, from equation (i), we get

$E\n\n=b^2c^(-1)\n\n=8^2* (-4)^(-1)\n\n\n=(64)/(-4)\n\n=-16.$

Thus, option (B) is correct.

Answer 2

Answer: b²c-¹ = (8)²(–4)-¹ = 64(–¼) = –16

Which is bigger 2/5 or 4/9

Answers

The easiest way to solve this comparison without any unusual comparisons is to find a common denominator for the two fractions.

2/5 = 18/45
4/9 = 20/45

Since 20/45 is bigger than 18/45, we know that 4/9 is greater than 2/5
