Write the following exponents in expanded form a) 5² b) 6⁸ c) 9⁵

a- 5 x 5

b- 6 x 6 x 6 x 6 x 6 x 6 x 6 x 6

c- 9 x 9 x 9 x 9 x 9

Step-by-step explanation:

the index represents how many times the number is to be multiplied.

5² = 5 x 5 = 25

6⁸ = 6 x 6 x 6 x 6 x 6 x 6 x 6 x 6 = 1679616

9⁵ = 9 x 9 x 9 x 9 x 9 = 59049

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
