Answer:
4 1/2 * 5 6/7 = 26 and 5/14
or 369/14
Step-by-step explanation:
4 1/2 * 5 6/7
convert to improper fractions
4 and 1/2 = 9/2
5 and 6/7 = 41/7
4 1/2 * 5 6/7 = (9/2)*(41/7) = 369/14 = 26 and 5/14
4 1/2 * 5 6/7 = 26 and 5/14
Question translated into English:
Write in standard form: 0.898×10⁵
Answer:
Standard form is given by the form A×10ⁿ
Where A is a value in unit and 'n' is for all integers
0.898 is not in unit so we need to rewrite this as 8.98×10⁻¹
Write them together with the 10⁵, we have
8.98×10⁻¹×10⁵ = 8.98×10⁻¹⁺⁵ = 8.98×10⁴

Answer:
If the equation is log(21+4) = log(14-31 + x)*(-1), then x = -8
Step-by-step explanation:
log(21+4) = log(14-31)
or
log(21+4) = log(14-31 + x)*(-1)
log (25 ) = log (-17 + x)(-1)
25 = (-17 + x) *(-1)
-25 = -17 + x
x = -8
