Question

find the value (1/2)-2+(1/3)-2+(1/4)-2​

Answer 1

Answer:

According to your question we have to solve the sum given above

so let's solve

it's difficult for some students to solve fractional sum

$(\frac{1}{2})- 2 + (\frac{1}{3}) - 2 + ( \frac{1}{4}) - 2$

we will it solve by using BODMAS rule

$\frac{1}{2} + \frac{1}{3} + \frac{1}{4} - 2 - 2 - 2 \\ \\ = \geqslant \frac{6 + 4 + 3}{12} - 2 - 2 - 2 \\ \\ = \geqslant \frac{13}{12} - 6 \\ \\ = \geqslant \frac{13}{12} - \frac{6}{1} \\ \\ = \geqslant \frac{13 - 72}{12} \\ \\ = \geqslant \frac{ - 59}{12}$

Answer 2

WE CHANGED THE POWER INTO POSITIVE SO THAT WE CAN SOLVE THAT FURTHER.
