( 2/3 a^2b^2)^2·(−3ab)^4

german

Solving the expression: $(\frac{2}{3}a^2b^2)^2(-3ab)^4$ we get $36a^8b^8$

Step-by-step explanation:

We need to solve the expression: $(\frac{2}{3}a^2b^2)^2(-3ab)^4$

Solving:

Using exponent rule: $(a^b)^c=a^{bc}$ and another rule: $x^a.x^b=x^{a+b}$

$(\frac{2}{3}a^2b^2)^2(-3ab)^4\\=\frac{4}{9}a^4b^4(81a^4b^4)\\=\frac{4}{9}*81a^{4+4}b^{4+4}\\=4*9a^8b^8\\=36a^8b^8$

So, solving the expression: $(\frac{2}{3}a^2b^2)^2(-3ab)^4$ we get $36a^8b^8$

The loudness, L, measured in decibels (Db), of a sound intensity, I, measured in watts per square meter, is defined as L = 10 lo

Inessa [10]

Answer:

50 Db

Step-by-step explanation:

we know that

The loudness in decibels is given by the formula

$L = 10log(\frac{I}{I_0})$

where

I = sound intensity in watts per square meter (Watts/m^2)

I₀ = reference intensity, = 10^(-12) Watts/m^2

For I=10^(-7) Watts/m^2

substitute in the formula above and solve for L

$L = 10log(\frac{10^{-7} }{10^{-12}})$

$L = 10log(10^{5})$

$L = 10 (5)=50\ Db$
