Question

11. The diameter of Mars is about 9⁴ kilometers. Write 9⁴ in expanded form. Then find its value.

a. 9⁴ = 9x4 = 36
C. 9⁴ = 9x9 x 9 x9= 6, 165
b. 9⁴ =9+9+9+9=36
d. 9⁴=9x9 x 9 x9= 6,561

Answer 1

9⁴ means 9 multiplied by itself 4 times. The expanded form is 9 x 9 x 9 x 9, which equals 6561.

Step-by-step explanation:

The question asks for the expanded form of 9⁴ and then to calculate its value. The notation 9⁴ signifies 9 raised to the power of 4, meaning 9 multiplied by itself 4 times.

Therefore, the expanded form of 9⁴ is 9 x 9 x 9 x 9.

To find the value, you multiply 9 by itself four times:

9 x 9 = 81,

81 x 9 = 729,

729 x 9 = 6561.

Hence, the value of 9⁴ is 6561.
