Multiply x^1/4 times x^5/8
Leno4ka [110]
Multiplying exponents with the same base means we just have to add the exponents. We can multiply both the numerator and denominator of 1/4 by 2 to get 2/8, and adding 2/8 and 5/8, we get 7/8. So x^1/4 times x^5/8 is x^7/8.

suzanne is running a 5km race. so far she has ran 1,250m. how many more meters does she need to run to complete the race?
natita [175]

Answer: 3750 m

Step-by-step explanation:

Remember that there are different units; one is in km and the other is in m

I’ll go from km to m

1 km = 1000 m

Therefore 5 km = 5 x 1000 m

5km = 5000 m

Now, we just subtract to find how much more Suzanne have to run

5000 m - 1250 m = 3750 m
