Sole the equation x^2=16

x = ± 4

Step-by-step explanation:

Given

x² = 16 ( take the square root of both sides )

x = ± = ± 4

That is x = - 4, x = 4

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
