Solve the equation: 5^(3t)=13

jonny [76]

Answer:

0.531 (3 s.f.)

Step-by-step explanation:

${5}^{3t} = 13 \\ lg {5}^{3t} = lg13 \: \: \: \: (log \: both \: sides) \\ 3t(lg5) = lg13 \\ 3t = \frac{lg13}{lg5} \\ t = \frac{1}{3} ( \frac{lg13}{lg5} ) \\ t = \frac{lg13}{3lg5} \\ t = 0.531 \: (3 \: s.f.)$

Power rule is used for the 3rd step.

Let p = x2 + 6.<br> Which equation is equivalent to (22 + 6)2 – 21 = 4x2 + 24 in terms of p?

Alona [7]

Answer:

$\frac{35}{4} =p$

Step-by-step explanation:

p= $x^{2} +6$ ,

(22+6)2-21= $4x^{2} +24$

44+12-21= $4x^{2} +24$

35= $4x^{2} +24$ ,

If you factor out the equation, you get that 35=4p(if you factor it out)

Therefore, $\frac{35}{4} =p$
