Answer:
0.143
Step-by-step explanation:
7 / 7³ x 7 Start with the exponents first
7 / 343 x 7 Divide 7/343
0.02 x 7 Multiply 0.02 x 7
7^(1-3+1) = 7^-3
Here is the rule you should know: when multiplying powers of the same base you add the exponents ans when dividing powers of the same base you subtract the exponents.
Also, if there is no number at the exponent, it is 1.
Option 2
It's a rotation
203
17*7=119
12*7=84
84+119=203
18.84
3.14 · 6
k = +10 or -10
It's given in the question that the roots of the eqn. are real and equal. So , the discriminant of the eqn. should be equal to 0.
