Remember that an exponent means repeated multiplication.

The exponent of 4 means you have four \big(b^2\big)'s mutiplied together:

      \big(b^2\big)\cdot\big(b^2\big)\cdot\big(b^2\big)\cdot\big(b^2\big)

And then each exponent of 2 inside means you have two b's multiplied inside each set of parentheses.:  

    \big(b\cdot b\big)\cdot\big(b\cdot b\big)\cdot\big(b\cdot b\big)\cdot\big(b\cdot b\big)

There are 8 b's there when you expand this out.

erastova [34]

Answer: 3432.56

Step-by-step explanation: Everything is on the attached file, enjoy!!! If you have any further questions, just ask me, I'd be glad to help!

Alert: IDK if it is attached, so sorry if it isn't i'll try to explain it.

2490.05 is the initial value how much leo started with.

2.5% + 100% = 1.025

weekly =13weeks

multiply 1.025 by the sqrt of 13 since that's the amount of weeks.

that gets you 3432.56.

What is the probability that you would obtain a sum of 7 or a sum of 11 on the first roll? (Rolling two dice.)
crimeas [40]

Answer:

2/9

Step-by-step explanation:

Total outcome = 36

Sum of 7 = 6

Prob of sum of 7 = 6/36

Sum of 11 = 2

Prob of sum of 11 = 2/36

Prob of sum of 7 or 11 = 6/36+2/36

Prob of sum of 7 or 11 = (6+2)/36

Prob of sum of 7 or 11 = 8/36 = 2/9
