Select the best answer from the choices provided

The correct answer option is d. 9.

Step-by-step explanation:

We are given an expression and we are supposed to simplify it.

We can also write as .

We know the power rule which means that to raise a power to a power you need to multiply the exponents.

So multiplying the exponents to get:

3 gets cancelled by 3 so we are left with:

Therefore, the correct answer option is d. 9.

27^2/3

=(3^3)^2/3

= 3^2

= 9

Answer

d. 9

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
