what is the relationship between 5.34 x 10^5 and 5.34 x 10^-2 is it greater or lesser than? for 5.34 x 10^5? will give brainlies
Romashka-Z-Leto [24]

the relationship between 5.34 x 10^5 and  5.34 x 10^-2

5.34 x 10^5 = 5.34*100000= 534000

5.34 * 10^-2  , for exponent -2 we move the decimal point 2 places to the left

5.34 x 10^-2= 0.0534

Now we compare 534000  and 0.0534

0.0534 is 10,000,000 times less than 534000

Or we can say  534000 is 10,000,000 times greater than 0.0534

5.34 x 10^5 is 10,000,000 times greater than 5.34 x 10^-2

Simplify x^3 y^3 / x^3 y^3
Marysya12 [62]

Answer:

\frac{1}{y}

Step-by-step explanation:

When simplifying an exponent a way to do is to expand the exponent. This means that it will now be

\frac{x*x*x*y*y*y}{x*x*x*y*y}

Whenever you see an x or y on the numerator and denominator cross it out because it is the same thing as 1

When you cross out all of the x's and y's the only variable left is y in the denominator. This means that the answer is \frac{1}{y}
