Which of the following is equivalent to the expression shown (0.2x-1)+(0.3-0.01x)

Mars2501 [29]

Answer:

0.07x - 0.002x^2 - 0.3

Step-by-step explanation:

Given the expression shown (0.2x-1)+(0.3-0.01x)

Expand

(0.2x-1)+(0.3-0.01x)

= 0.2x(0.3) - 0.2x(0.01x)-1(0.3) + 1(0.01x)

= 0.06x - 0.002x^2 - 0.3 + 0.01x

= 0.06x+0.01x - 0.002x^2 - 0.3

= 0.07x - 0.002x^2 - 0.3

This gives the required expression

Simplify and write the answer in exponential form 3x^4 × y^4 x^4

RideAnS [48]

Answer:

The simplified expression in the exponential form will be: $3x^8y^4$

Step-by-step explanation:

Given the expression

$3x^4\times \:y^4x^4$

simplifying the expression and writing the answer in exponential form

$\mathrm{Apply\:exponent\:rule}:\quad \:a^b\times \:a^c=a^{b+c}$

$x^4x^4=x^{4+4}$

so the expression becomes

$3x^4\times \:y^4x^4=3x^{4+4}y^4$

$=3x^8y^4$ ∵ $\mathrm{Add\:the\:numbers:}\:4+4=8$

Therefore, the simplified expression in the exponential form will be: $3x^8y^4$
