6^2-4(6)+3

Solution

6^{2} - 4 (6) + 3

15

Solution steps

6^{2} - 4 (6) + 3

Follow the PEMDAS order of operations

Calculate exponents

6^{2} : 36

6^{2}

6^{2} = 36

= 36

= 36 - 4 (6) + 3

Multiply and divide (left to right)

4 (6) : 24

4 (6)

Apply rule:

(a) = a

(6) = 6

= 4 \cdot 6

Multiply the numbers:

4 \cdot 6 = 24

= 24

= 36 - 24 + 3

Add and subtract (left to right)

36 - 24 + 3 : 15

36 - 24 + 3

36 - 24 = 12

= 12 + 3

12 + 3 = 15

= 15

= 15

\frac{1}{2} (1 + \frac{4}{5})

\frac{( 3 ) ^{4} - 81}{( 3 ) ^{2} + 8 ( 3 ) + 15}

[(3 - 5 (2 - 4) + 10 \div (- 3 - 2))]

10 + 2 (9 - 5) - \frac{16}{8}

90 - (25 + (5 \times 2 - 1) + 3)
