simplify (4x^5y^4)*(5x^5y^4)

simplify

(4 x^{5} y^{4}) \cdot (5 x^{5} y^{4})

20 x^{10} y^{8}

Solution steps

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

Apply exponent rule:

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

x^{5} x^{5} = x^{5 + 5}

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

Add the numbers:

5 + 5 = 10

= 4 y^{4} \cdot 5 x^{10} y^{4}

Apply exponent rule:

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

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

= 4 \cdot 5 x^{10} y^{4 + 4}

Add the numbers:

4 + 4 = 8

= 4 \cdot 5 x^{10} y^{8}

Multiply the numbers:

4 \cdot 5 = 20

= 20 x^{10} y^{8}

(x^{2} + 1) (2 x) x

4.6 \cdot 1 0^{- 7} \frac{( 299792458 )}{2 4}

e^{- 3 t} \frac{( e ^{t} - e ^{- t} )}{2}
