simplify

(4 x^{3} y^{4}) (5 x^{2} y^{3})

20 x^{5} y^{7}

Solution steps

(4 x^{3} y^{4}) (5 x^{2} y^{3})

Apply exponent rule:

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

x^{3} x^{2} = x^{3 + 2}

= 4 y^{4} \cdot 5 x^{3 + 2} y^{3}

Add the numbers:

3 + 2 = 5

= 4 y^{4} \cdot 5 x^{5} y^{3}

Apply exponent rule:

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

y^{4} y^{3} = y^{4 + 3}

= 4 \cdot 5 x^{5} y^{4 + 3}

Add the numbers:

4 + 3 = 7

= 4 \cdot 5 x^{5} y^{7}

Multiply the numbers:

4 \cdot 5 = 20

= 20 x^{5} y^{7}

3.4 \cdot 1 0^{- 3}

3.4 \cdot 1 0^{- 5}
