simplify 3x^2(15yx)

Solution

simplify

3 x^{2} (15 y x)

45 x^{3} y

Solution steps

3 x^{2} (15 y x)

Apply exponent rule:

a^{b} \cdot a^{c} = a^{b + c}

x^{2} x = x^{2 + 1}

= 3 \cdot 15 y x^{2 + 1}

Add the numbers:

2 + 1 = 3

= 3 \cdot 15 y x^{3}

Multiply the numbers:

3 \cdot 15 = 45

= 45 x^{3} y

e^{- 8 x} d x

e^{x^{2}} \cdot e^{y}

(7 x^{2} y^{2}) (x^{3} y)

5.4 \cdot 1 0^{- 3} \cdot 7.5 \cdot 3600

7.05 \cdot 1 0^{- 2} \cdot 4 \cdot 3.14 \cdot (110)^{2}
