simplfy 5/ (8+�ã7)
I will assume that by "simplify" you mean rationalize
5/(8+√7)
= 5/(8+√7) * (8-√7)/(8-√7)
= (40 - 5√7)/(64 - 7)
= (40 - 5√7)/57
thank you.
To simplify the expression 5/(8+7), follow these steps:
Step 1: Begin by evaluating the expression inside the parentheses, which is 8+7.
8 + 7 = 15
Step 2: Now that we have the simplified expression, substitute it back into 5 / (8+7).
5 / 15
Step 3: To simplify the final expression, divide the numerator (5) by the denominator (15).
5 ÷ 15 = 1/3
Hence, the simplified expression of 5 / (8+7) is 1/3.
