Answer:
12 x^5y^12
Step-by-step explanation:
3x^2y^5 * 4x^3y^7
Multiply the constants
3*4 = 12
Multiply the x terms
x^2 * x^3
We know a^b* a^c = a^(b+c)
x^(2+3) = x^5
Multiply the y terms
y^6 * y^7 = y&(5+7) = y^12
Put them back together
12 x^5y^12
Simplification of (-2/5) divided by (8/9) times (2/9) divided by (-1/3) is 0.3
<em><u>Solution:</u></em>
Given that,
Simplify (-2/5) divided by (8/9) times (2/9) divided by (-1/3)
Here "times" represent multiplication
<em><u>The above sentence can be written mathematically as:</u></em>

Convert the problem to multiplication by changing the division sign to multiplication. When we change division sign to multiplication, the fraction becomes reciprocal

Cancelling the common terms in numerator and denominator,

Multiplying terms in numerator and denominator,

Negative sign in numerator and denominator cancels each other

Reducing to lowest terms we get,

In decimal form we get,

Thus solution to given expression is 0.3
