<u>Solution for question 1:</u>
Put it in this format:
Solving;
2(²-³) × 10^(15-9)
2^-1 × 10^6 = 1/2 × 10^6
That gives 5 × 10^5
<u>Solution to question 2:</u>
Solving;
2^(1 - 2) × 10^(-5 + 12)
= 1/2 × 10^7
That gives;
5 × 10^6
Answer:
x=2+ or x= 2-
Step-by-step explanation:
Okay, if Susan bought nine washcloths, we know that the number nine will be in the equation. We know the cost is $39.90 for each one, so all you have to do is multiply them by each other. This would be the equation:
9x39.90=359.10
310 - 30w would be an expression for this problem
