Expression 7 + 9/4 can also be written in the form ofc÷a^b . A = b= c=

Arlecino [84]

<h3>Answer: a = 37, b=2 and c=2.</h3>

Step-by-step explanation: Given expression 7 + 9/4.

Let us simplify given sum of fractions by taking common denominator, we get

$\frac{7}{1} +\frac{9}{4}$

Common denominator is 4.

Therefore, multiplying top and bottom of 7/1 by 4, we get

$\frac{7\times 4}{1\times 4} +\frac{9}{4} = \frac{28}{4} +\frac{9}{4}$ .

We got same denominators,

So, combining top numbers, we get

$\frac{28+9}{4}=\frac{37}{4}$

We can read 37/4 as 37 divided by 4.

Therefore, 37 ÷ 4.

Let us write 4 as the power of 2.

$4= 2^2.$

37 ÷ $2^2$

On comparing c÷a^b and 37 ÷ 2^2, we can see..
