Answer:
(I will do 3 of these for you and if you still do not understand I will do the rest)
Step-by-step explanation:
Keep in mind that when they put the exponent you will have to multiply that number that many times. Ex. (3)² = 3 x 3
b. 14/7 x 14/7 = 14/49 = 14/19 = 2/7
c. 0.92 x 0.92 = 0.8464
d. 31 x 31 x 31 = 29791
Hope this helps :)
