Answer:

5 quarters 12 dimes

Step-by-step explanation:

The quarters have to be a odd number or you wouldn't have the 5 at the end of the number. Because there are "two more then twice as many" dimes then quarters the number of quarters has to stay down. 3 to 5 is a good guess to start. from there you can add up the dimes until it all fits together

\rule{200pt}{3pt}

<h2><u>☼︎</u><u>To Find :</u></h2>

  • Area of the room.

\rule{200pt}{3pt}

<h2><u>☼︎</u><u>Solution :</u></h2>

Simplify (5.1)(5.12)4.<br><br> (5.1)6<br> (5.1)7<br> (5.1)8<br> (5.1)9
Andru [333]

The simplified expression of (5.1)(5.1^2)^4 is (5.1)^9

<h3>How to simplify the expression?</h3>

The expression is given as:

(5.1)(5.12)4

Rewrite the expression properly as follows:

(5.1)(5.1^2)^4

Rewrite the expression properly as follows:

(5.1)(5.1^2)^4 = (5.1) * (5.1^2)^4

Apply the power law of indices

(5.1)(5.1^2)^4 = (5.1) * (5.1^8)

Apply the power law of indices

(5.1)(5.1^2)^4 = (5.1)^(1 + 8)

Evaluate the sum

(5.1)(5.1^2)^4 = (5.1)^9

Hence, the simplified expression of (5.1)(5.1^2)^4 is (5.1)^9
