30 x 25 = 750

750 + 30^7:

30 x 30 x 30 x 30 x 30 x 30 x 30= 21870000000.

21870000000 + 750

=21870000750.

A bag contains green marbles and blue marbles,

dexar [7]

There are 13 green marbles in the bag.

Step-by-step explanation:

Total marbles = 18

Let,

Green marbles = x

Blue marbles = y

According to given statement;

The number of green marbles is 2 less than 3 times the number of blue marbles.

x = 3y-2 Eqn 1

x+y=18 Eqn 2

Putting value of x from Eqn 1 in Eqn 2;

$(3y-2)+y=18\\3y-2+y=18\\4y=18+2\\4y=20$

Dividing both sides by 4

$\frac{4y}{4}=\frac{20}{4}\\y=5$

Putting y=5 in Eqn 1

$x=3(5)-2\\x=15-2\\x=13$

There are 13 green marbles in the bag.

Simplify <br> (5x^2y^3)^2x(2x^3y^4)^3

Misha Larkins [42]

Remember
$(abc)^x=(a^x)(b^x)(c^x)$
and
$(x^m)(x^n)=x^{m+n}$
and
$(x^m)^n=x^{mn}$
so
I'm going to assume that that x after the 2 exponent is multiply and not a variable to be multiplied, if it is go to option 2
$(5x^2y^3)^2(2x^3y^4)^3$ =
$(5^2)((x^2)^2)((y^3)^2)(2^3)((x^3)^3)((y^4)^3)$ =
$(25)(x^4)(y^6)(8)(x^9)(y^{12})$
$200x^{13}y^{18}$

2. if that x was a variable and nod a multiply then
$200x^{14}y^{18}$
