Simply the following 2m⁵×5m³×7m²

Ganezh [65]

Answer:

$2m^5\cdot 5m^3\cdot 7m^2=70\cdot m^{10}$

Step-by-step explanation:

Simplify the expression

$2m^5\cdot 5m^3\cdot 7m^2$

Calculate the product of the coefficients:

2*5*7=70

Compute the product of the variables. Since they are all the same letter, sum their exponents:

$m^5\cdot m^3\cdot m^2=m^{5+3+2}=m^{10}$

Combine the results:

$\boxed{2m^5\cdot 5m^3\cdot 7m^2=70\cdot m^{10}}$

Tanzania [10]

Answer:

step 2

Step-by-step explanation:

we have

$x^{2} +10x-49=0$ ---> given problem

step 1

Move the constant to the right side

$x^{2} +10x=49$

the step 1 is correct

step 2

Complete the square

$x^{2} +10x+5^2=49+5^2$

$x^{2} +10x+5^2=74$

The step 2 is not correct

step 3

Rewrite as perfect squares

$(x+5)^{2}=74$

step 4

take square root both sides

$x+5=\pm\sqrt{74}$

step 5

Find the values of x

$x=-5\pm\sqrt{74}$

$x=-5+\sqrt{74}$

$x=-5-\sqrt{74}$
