Question

Evaluate the expression 4m^(-3) n^(-5) when m = 2 and n = 1.

a) 0.0625
b) 0.125
c) 0.25
d) 0.5

Answer 1

To evaluate the expression 4m^(-3) n^(-5) when m = 2 and n = 1, substitute the values of m and n into the expression. The answer is 0.5.

Step-by-step explanation:

To evaluate the expression 4m^(-3) n^(-5) when m = 2 and n = 1, we substitute the values of m and n into the expression.

Replacing m with 2 and n with 1, we get:

4(2)^(-3) (1)^(-5) = 4(1/8)(1) = 4/8 = 1/2 = 0.5

Therefore, the answer is d) 0.5.
