multiply with monomial

The answer is B

Step-by-step explanation:

You can multiply it using Indices formula, a^m × a^n = a^(m+n) :

(-4y)(-9y⁹)

= (-4×-9)(y×y⁹)

= 36y^(1+9)

= 36y^10

Explanation: To simplify this problem, we can first multiply our coefficients hut we must add the exponents on the like bases.

This idea is called the product rule.

So we have -4 · -9 which is 36.

Now add the exponents.

Think of the as .

So we add our exponents to get .

So our answer is .

70

step-by-step explanation:

2*5=10

4*15=60

60+10=

70

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
