Answer:
The reasonable estimate for the problem is 8.
Step-by-step explanation:
Given:
The problem -3/2 times (-5 1/4)
Now, convert the mixed fraction into improper.
Then, multiply the numerator with numerator and denominators with denominator.
Whenever the same signs multiply the product are in positive.
Now, convert the resulting improper fraction into mixed.
.
Estimate value of 7 7/8 is 8.
Therefore, the reasonable estimate for the problem is 8.
Answer:
4x^-4/9y^6
Step-by-step explanation:
If the exponent is outside the bracket, it means that all the terms inside will be raised to that exponent. This means that:
(2x^-2 / 3y^3)^2 = 2^2*(x^-2)^2 / 3^2*(y^3)^2
When exponents are raised to an exponent, the exponents are multiplied together, so (x^-2)^2 will = x^(-2*2) = x^-4
Going through:
2^2*(x^-2)^2 / 3^2*(y^3)^2
=4*x^-4 / 9*y^6
=4x^-4/9y^6
Hope this helped!
