Question

Compute the following:
$(a) (3)^{4}$
$(b) ( - 5)^{2}$
$(c) ( - 1)^{78}$
$(d) {11}^{3}$
$(e)( - 4)^{3} \times ( - 10)^{3} \times ( - 1)^{789}$
$(f) (50)^{2}$

​

Answer 1

Step-by-step explanation:

a. 3×3×3×3=81

b. -5×(-5)=+25

c. (-1)⁷⁸=+1 {because if the power is even number the value will be positive and if power is odd the value will be negative}

d. 11×11×11=1331

e. (-4)³×(-10)³×(-1)⁷⁸⁹= (-64)×(-1000)×(-1)=(-64000)

f. (50)²=50×50 = 2500

hope it helps:)
