What is the solution to (4x 103) x(3×104) written in scientific notation?

Step-by-step explanation:

4 x 103 = 412, 3 x 104= 312

412 x 312 = 128,544

number has to be between one and ten and show significant digits.  the decimal has to be moved five tome to the left creating the number 1.28544.  to move the decimal back you have to multiply by 10 to the 5th power. Yielding 1.28544 x 10^5

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
