What is the exact value of x? 5⋅21^5x=16

IRINA_888 [86]

Answer:

x= 16 /20420505

Step-by-step explanation:

Let's solve your equation step-by-step.

5(215)x=16

Step 1: Simplify both sides of the equation.

20420505x=16

Step 2: Divide both sides by 20420505.

20420505x /20420505 = 16 /20420505

x= 16 /20420505

2/5 + k/4 = 9/10 (solve with work)

Alla [95]

The LCD of 2/5 + k/4 = 9/10 is 20. Applying this LCD, we get:

8 + 5k = 18. Subtracting 8 from both sides: 5k = 10. Then k = 10/5, or k = 2.

$3x^{2} +1=28$

Step 1 : subtract 1 from both sides

$3x^{2} =27$

Step 2 : Divide both sides by 3

$\frac{\frac{3x^{2} }{3} }{\frac{27}{3} }$

$x^{2} = 9$

Step 3 : Find the square root of 9

$\sqrt{9} = 3$

x= (-3,3)

remember negative × negative = positive
