Question

question) simplify and express the result in power notation with positive exponent. 2^-3*(-7)^-3 pls tell step by step

Answer 1

Answer:

1/14^-3

Step-by-step explanation:

2^-3 x(-7)^-3

(so when we have same powers(number of power is same) we multiply the numbers and write the power just once)

2^-3 x(-7)^-3

= 14^-3 (just like that i multiplied 2 and 7, got 14 and wrote the power -3 only once)

(And now to make express the power as positive we will we will take the number along with is power in the denominator and remove the negative sign. )

1/14^-3
